Cummins Onan - products

Cummins Onan offers a complete line of residential emergency standby systems. You can depend on clean, quiet power whether your needs call for a permanently-installed standby system or a portable solution.

Our permanently-installed models are neighborhood-friendly, and run on natural gas or propane. They are no more conspicuous than a central air conditioning unit and are typically linked directly to your permanent fuel supply. During a power interruption, the Cummins Onan residential emergency standby system will automatically deliver the power to keep your home running smoothly. And it will reset once the power returns.

The sections below will help you understand the advantages of one fuel compared to another.

Natural Gas Generator Sets

A natural gas generator connects directly to a natural gas line for clean, safe and quiet operation.

Advantages:

Usually unlimited fuel source - refueling not necessary

Clean burning

Almost always available during power outages

No unsightly tank required

Disadvantages:

May be unavailable during natural disasters (earthquakes, etc.)

Lower power output (30% less BTU's per unit than gasoline)

Larger tanks are not aesthetically pleasing (unsightly)

Fuel system plumbing results in higher installation cost

Not available in many areas

Propane Generator Sets

These generators are designed to be fueled by either LP vapor or LP liquid withdrawal. They also connect directly to a natural gas line for clean, safe and quiet operation.

Advantages:

Long shelf life

Clean burning

Easily stored in both large tanks or in smaller 5-10 gallon cylinders

Obtainable during power outages - gas stations may be unable to pump other fuels during an area wide outage but, LP tanks are usually stocked full

Home delivery available for larger tanks is commonplace

Disadvantages:

Pressurized cylinder of flammable gas

Fuel system is more complicated (increased possibility of failure)

Larger tanks are not aesthetically pleasing (unsightly)

Fuel system plumbing results in higher installation cost

Some local ordinances prohibit the use of high pressure LP in residential applications

Other products and services from Cummins Onan Generators

Generally, a Cummins Onan residential home standby generator set offers many features not found on portable generator sets, such as a more sophisticated control system, a fully weather–protective enclosure, significantly quieter operation, and more capacity so you can power more conveniences.

Automatic transfer switches, capable of automatic operation without operator intervention, perform the basic function of transferring the load to the available power source.
Should the utility fail, the transfer switch automatically switches the electrical load from the utility to the generator.
The utility (normal power source) is backed up by a generator (emergency power source).

Their revolutionary design makes these generator sets up to 15 dBquieter than other diesel-powered generators, and quieter than most gasoline sets.
The Quiet Diesel Series models are the heavy-duty choice when low noise and low vibration are required.

These include exceptionally low noise and vibration, easy installation, diagnostic capability and digital regulation which maintains voltage stability as loads change.
The 5500 kW and above models are designed to perform consistently in applications where dependability and high-quality power are essential.
The 4000 kW and under generator sets are ideal for light and medium-duty applications with small size and weight constraints.
